Fig. 4: Thickness of ejecta from a 45° impact with 12 km/s within 30° in latitude from the antipode.
From: Impactor material records the ancient lunar magnetic field in antipodal anomalies
Panel a represents the ejecta sourced from the impactor and b is the total ejecta (both from the impactor and the target). The horizontal dotted line represents the direction of the impactor (see arrow and caption in Fig. 2). Note that each circled point represents the surface area of a spherical cap with a diameter of 1°, in which we sum the volume of ejecta and derive its thickness. The arc-shaped patterns on the right side of the antipode appear because of the numerical resolution and the choice of surface area size (Supplementary Note 3 and Fig. 9).
